In Simi Valley and across Ventura County, a whole home renovation runs between $100,000 and $500,000 — depending on the size of your home, the scope of the work, and the finish level you’re going for. That’s a wide range, and it’s wide for a reason: a cosmetic refresh of a 1,600 sq ft home is a fundamentally different project than a gut renovation of a 2,800 sq ft property with a new kitchen, two new bathrooms, hardwood floors throughout, and structural changes.

What “Whole Home Renovation” Actually Means
The term gets used loosely. Some homeowners mean a full gut-to-studs rebuild. Others mean updating every room without changing the structure. Both qualify — and the cost difference between them can be $150,000 or more.
Here’s how we define the three tiers we see most often in Ventura County:
Cosmetic Renovation: New flooring, paint, countertops, fixtures, and appliances throughout. No structural work, no layout changes, no major plumbing or electrical. This is the lowest-cost path to making every room feel new.
Mid-Range Full Renovation: Full kitchen and bathroom remodels, new flooring throughout, updated lighting, fresh paint, and possibly a laundry room refresh. May include minor layout tweaks. This is the most common whole-home renovation scope we handle in Simi Valley.
Full Gut Renovation: Walls opened, plumbing and electrical rerouted, layout changes, new kitchen and bathrooms completely rebuilt, all new finishes. Often required in homes built before 1990 where the original systems are at or past their service life.
Whole Home Renovation Cost by Scope — Simi Valley 2026
These are realistic ranges based on current material and labor costs in the Simi Valley and Ventura County market.
Cosmetic Renovation: $50,000–$100,000
This covers flooring throughout, interior paint, new countertops, updated fixtures and hardware, lighting upgrades, and appliance replacements. No structural changes. No plumbing or electrical rerouting. For a 1,600–2,200 sq ft home in Simi Valley, this scope typically lands between $55,000 and $85,000.
It’s the right move when the bones of the home are solid and the goal is modernization without complexity. Many homeowners in East Simi Valley neighborhoods built in the late 1980s and 1990s take this approach before listing.
Mid-Range Whole Home Renovation: $100,000–$250,000
This is the most common scope we execute in Ventura County. It includes:
- Full kitchen remodel with new cabinetry, countertops, appliances, and layout refinements
- One or two full bathroom remodels
- New flooring throughout
- Interior paint and lighting upgrade throughout
- Possible laundry room update
- Possible minor structural work (removing a non-load-bearing wall, opening a kitchen to a living room)
For a 1,800–2,400 sq ft Simi Valley home, this scope typically lands between $130,000 and $210,000. The biggest variables are finish level and how many bathrooms are in scope.
High-End or Gut Renovation: $250,000–$500,000+
This scope includes everything above plus structural changes, full plumbing and electrical upgrades, a new primary suite, or significant layout reconfiguration. Some projects in this range also include ADU additions or room additions running concurrently.
Homes built before 1985 often require more in this category than homeowners expect — galvanized plumbing, outdated electrical panels, and original HVAC systems can each add $15,000–$40,000 to the project. We see this routinely in Simi Valley neighborhoods like Royal and Stagecoach.
Line-Item Cost Breakdown — Major Components
Here’s what individual components cost in the Simi Valley and Ventura County market in 2026. These are realistic installed costs, not lowball estimates.
| Component | Typical Cost Range |
|---|---|
| Full kitchen remodel | $35,000–$80,000 |
| Full bathroom remodel (per bath) | $15,000–$40,000 |
| Flooring — whole house (LVP or engineered hardwood) | $8,000–$25,000 |
| Interior paint — full home | $4,500–$9,000 |
| Electrical panel upgrade + lighting | $6,000–$18,000 |
| Plumbing reroute or upgrade | $8,000–$30,000 |
| HVAC replacement or upgrade | $8,000–$22,000 |
| Laundry room refresh | $3,500–$8,000 |
| Windows (full home replacement) | $15,000–$40,000 |
| Insulation (full home) | $4,000–$10,000 |
These numbers assume standard residential construction in Simi Valley. Projects in Thousand Oaks and Moorpark with higher-end finish expectations often run 15–25% above these midpoints.
What Drives Costs Up (And What Doesn’t)
The single biggest driver of whole home renovation cost is scope creep — projects that start as a mid-range renovation and grow as walls open up. Here’s what we see most often:
What pushes costs up:
- Older homes (pre-1985) with galvanized pipes, original panels, or inadequate insulation
- Layout changes requiring structural engineering
- Custom or imported materials with longer lead times
- Permit complexity (Ventura County permit processing for large scopes can add 6–10 weeks)
- Finishes above the market standard for the neighborhood (diminishing ROI above a certain point)
What doesn’t necessarily cost more than expected:
- Flooring — LVP has gotten significantly more competitive; quality installs are running $4–$7/sq ft all-in
- Interior paint — often underestimated in quotes; get this itemized
- Kitchen cabinets — semi-custom cabinets hit a good price/quality balance for most Simi Valley projects

How Long Does a Whole Home Renovation Take?
Timeline depends on scope. Here are realistic estimates based on projects we’ve completed in Simi Valley, Thousand Oaks, and Moorpark.
Cosmetic Renovation: 6–10 Weeks
Flooring, paint, countertops, and fixture swaps can often run in parallel. A well-organized cosmetic renovation in a 1,800 sq ft home typically completes in 6–8 weeks with a full crew. The main delay risk is countertop lead times (2–4 weeks for quartz fabrication).
Mid-Range Whole Home Renovation: 3–6 Months
A full kitchen and two bathrooms plus flooring and paint needs proper sequencing. Rough plumbing and electrical happen before drywall. Kitchen cabinetry comes after drywall. Flooring happens after cabinets. Countertops are last. When you account for permit processing (Simi Valley’s building department currently runs 4–6 weeks for residential permits) and material lead times, 4–5 months is the realistic expectation.
High-End or Gut Renovation: 5–10 Months
Structural work adds design and engineering review time. Complex scopes with multiple subcontractors need careful scheduling to avoid idle weeks between trades. Projects in this range that go smoothly take 5–7 months. Projects with surprises — hidden water damage, undersized footings for an addition, asbestos in pre-1978 homes — can stretch to 9–10 months.
One thing that significantly affects timeline: having everything decided before construction starts. Homeowners who lock in their tile selection, cabinet style, and fixture choices before demo begins move through construction 3–6 weeks faster than those who decide during the build.
ROI: Does a Whole Home Renovation Pay Off?
In the Simi Valley and Ventura County market, a well-executed whole home renovation typically returns 60–75% of its cost in added property value. On a $200,000 renovation, that’s $120,000–$150,000 in added equity — while also giving you a completely updated home to live in.
The strongest ROI scenarios we see:
Buying a dated home and renovating before moving in. Homes built in the 1980s and 1990s in Simi Valley often sell at a discount precisely because they need full renovation. Buying at a discount and renovating can produce equity gains well above 75%.
Renovating to list in a supply-constrained market. Ventura County inventory remains low. Updated homes sell faster and significantly closer to asking than dated homes. A fully renovated home in Simi Valley or Moorpark typically commands $50,000–$100,000 more than a comparable non-updated home in the same neighborhood.
Multi-generational renovation. Families converting a garage, adding a primary suite, and refreshing the main living areas often see blended returns across multiple improvements.
One important note: finish levels matter. Renovating a Simi Valley home to Thousand Oaks luxury finishes — custom cabinetry, imported stone, high-end appliances — won’t produce 100% return if the neighborhood comps don’t support it. We help homeowners calibrate finishes to their neighborhood so they maximize return without over-building.
What to Ask Before Signing a Whole Home Renovation Contract
A project at this scope requires more diligence than a single-room remodel. Here’s what matters:
Is the contractor licensed and insured for general contracting? Whole home renovations require a General Contractor license (Class B) in California. Verify at cslb.ca.gov. Our license is #1066117.
Who pulls the permits? Every whole home renovation in Simi Valley, Thousand Oaks, and Moorpark requires permits for structural, electrical, and plumbing work. If a contractor offers to do the work without permits, walk away.
Do they provide a written, itemized contract? Line-item pricing lets you see what you’re paying for and compare bids accurately. A lump-sum quote is a red flag on a project this size.
What’s their change order process? In whole home renovations, surprises happen. Ask how changes are documented, priced, and approved before signing.
What’s the payment schedule? Never pay more than 10% upfront. California law limits deposits to 10% or $1,000 (whichever is less) for most residential projects. A contractor asking for 50% upfront before work begins is a major red flag.

Frequently Asked Questions
How much does a whole home renovation cost in Simi Valley?
A whole home renovation in Simi Valley typically costs between $100,000 and $500,000, depending on scope and finish level. A cosmetic refresh (flooring, paint, countertops, fixtures) runs $50,000–$100,000. A mid-range full renovation including kitchen, bathrooms, and flooring runs $130,000–$250,000. A high-end or gut renovation with structural changes runs $250,000–$500,000 or more.
How long does a whole home renovation take in Ventura County?
Cosmetic renovations take 6–10 weeks. Mid-range whole home renovations — full kitchen, bathrooms, flooring, and paint — typically take 3–5 months when permits are accounted for. High-end or gut renovations with structural changes run 5–10 months. Permit processing at Simi Valley’s building department currently adds 4–6 weeks to most project timelines.
Does a whole home renovation increase property value?
Yes. A well-executed whole home renovation in the Ventura County market typically returns 60–75% of its cost in added property value. Updated homes also sell faster and at prices significantly closer to asking. In Simi Valley and Moorpark, where many homes were built in the 1980s and haven’t been touched since, a full renovation can close a meaningful price gap versus recently updated neighborhood comps.
Do I need permits for a whole home renovation in Simi Valley?
Yes. Any whole home renovation that involves structural changes, electrical work, plumbing, or HVAC requires permits through the Simi Valley Building & Safety Division. Cosmetic-only work (paint, flooring, hardware swaps) generally does not require a permit. Working without required permits creates legal liability when you sell and can require costly remediation.
What’s the difference between a renovation and a remodel?
Renovation means restoring or refreshing what’s there (new finishes, updated fixtures, modern materials). Remodel means changing the layout or structure (removing walls, relocating the kitchen, adding square footage). A whole home renovation may include both elements — especially in Ventura County homes built in the 1980s where layouts are often closed-off and feel dated even after finishes are updated.
